CASTELLATED NUT.

Application led March 2,1921. ySerial No. 449,059.

To all whom t may concern; 1

Be it known that I, GEORGE EDWARD CARTER, a citizen of the United States, and `residing at Circleville, in the eounty of Pickaway and State of Ohio, have invente-d certain new and useful Improvements in Castellated Nuts; and I do hereby declarel the following tobe a full, clear, and exact description of the invention, such as will enable others skilledk in the art to which it` appertains to make and use the saine.

This invention relates to improvements in Fig. 4:'is a plank showingthe slot wallsB diverging inwardly and outwardly.

i In the form of the invention, I have shown a divergence in my form of slot from the usual form of slot employed at present in castellated nuts.

In Fig. 1 I haveI shown the form ofv the slots 1 as havingtheir side walls diverging inwardly on the are of a circle. This form of slotgreatly facilitates the inserting ofk cotter pins. y

In Fig. 2 I have shown the slots 2 as having their side walls diverging outwardly on the arc yof ya circle. This forni fof slot also greatly facilitates the inserting of cotter pins.

In Fig. 4I have shown the slot walls 3 nut wall. l

verge inwardly and outwardly-- The slots referred tocan he conveniently and rapidly cut hy the device and according tothe method described,r in the Letters Patent of the United States No. 1,498,231, dated upon an axis parallel to the axis of thenut.

It is obvious that I do not intendto confine myself strictly to having the side walls of the slots curved and diverge inwardly or outwardly, but I claim theJ right to vary these side walls with reference to radial lines or axes so long as the side walls diverge iii-y wardly or outwardly, or so long as they di- I claim:

1. A castellated nut having a side of its slot wall formed on the are of a circle, the axis of which is substantially parallel to the axis of the nut.

2. A castellated nut having the opposite y sides of its slot walls formed on the arcs of .circles the.' axes of which are substantially parallel to the axis of the nut.

A castellated nut having sides of its vserved that the axis of the cutting tool turns slot walls formed on the arcs of rcircles the axes of whicha-re substantially parallel to the axis of the nut said slots flaring at their ends. y z

l 4l. Afcastellated nut having a side of its slot wall formed on the arev of a circle the axis of which is substantially parallel tothe axis of the nut said slot flaring at one end. K f 5. A eastellated nut rhaving a crest formed with notches having a desired portion to snugly engage a cotter pin and expandingly tapered portions terminating on the inside,

and outside of the nut.

In testimony whereof I aflix my signature in the presence of two witnesses.
